To all whom t may concern.'

K Be it known that I,- OnMoNn E. HUNT, a citizen of the United States,and resident of Detroit, Wayne County, State of Michi an, have inventedcertain new and useful mprovements in Radiator Caps for Motor Vehicles,of which the following is a specification. i

This invention relates to motor vehicles and more particularly 4to llercaps for the radiators of such vehicles.-

The principal object of the invention is to provide a cap for theiilling opening of Vradiators which shall be permanently connected tothe latter and in which the hinge construction forl radiator and capshall be concealed `within the mouth of the radiator so as to protectthe hinge and preserve an attractive exterior appearance for the cap.

With these objects in view theinvention is embodied in referable form inthe construction hereinallter described and illustrated in theaccompanying drawings, in which drawings? 4 F ig. 1 is a perspectiveview of the front part of the hood of a motor vehicle and of theradiator and showing the invention applied to the filler mouth of theradiator,

Fig. 2 is a vertical section through the cap and filler mouth.

Fig. 3 is the top plan view partly broken away, and

F1 4 is a vertical section at right angles le Fig. 2 and showing amodified form of Rgeferring to the drawings, 10 indicates the shell of aradiator formed by va raised hollow cylindrical body projecting abovethe body of the part which is adapted to receive water poured from asuitable vessel into the open end of the mouth from whence it passes tothe radiator and other parts of the cooling system. This mouth 1sprovided with a cap 12 which is pivotally and permanently connected tothe filler month so that the latter may be readily uncovered or closedbut so that at the same time there is no danger ot losing the cap as inthose 'constructions in which the same is separable :trom the' mouth.

pivotally connecting they and 11 a filler mouth 10 and- Referring to theconstruction illustrated in Flgs. 1, 2 and 3, 13 is an arm fixed to theinner surface of the cap 12 and bent -at right angles to its attachingpart so as to extend downward having at its lower end pintles 14 which`engage in sockets in za U shaped bracket 15. The `bracket 15 has earsresting upon and secured to lugs 16, preferably formed integral with thewall of the filler mouth and extendin inwardly therefrom. Screws 17connect t e ears ystruction it will be seen that a simple concealedhinge is provided and one with which vthe ller cap may be readilyconnected.

The cap is provided with an exterior raised boss 18 having a notch 19adapted to be engaged by a s'prmg bail 20 which serves as a lockingmember to hold the cap in closed position.

In Fig/t another form ofV hinge is illustrated. l n this construction 21is the filler mouth, 22 the cap and 23 the spring locking bail. The capis provided on its under sur- A face with an arm 24 adapted to be bentdown into the interior of the filler mouth and having at its lower end apin or pins 25 which engage sockets in a link 26, which in turn ispivoted at 27 to a bracket member 28 depending from the lu 29. Thisconstruction at'ords a double Joint between the cap and the filler mouthwall and provides a simple connection that will permlt the cap to swingdown to a position substantially in a vertical plane. Having thusdescribed m l claim and desire to secureli is' invention what yLettersPatent 1. A motor vehicle radiator having a iller mouth, a cap therefor,an arm rigidlysecured to the cap and extending into the mouth, a pivotalconnection between the free end of the arm and the inner part of themouth, said arm being shaped to permit the cap to open on said pivotalconnection away from the mouth, and yieldin means for pressing the capagainst the en of the .mouth 2. A motor vehicle radiator having a llermou' h, a filler cap, an 4arm rigidly secured to said cap on the insidethereof and projectinto the iiller mouth and to the lugs. By this con`ing laterally therefrom, a hinge member secured in said mouth below theouter end thereof, and a pivoted connection between said arm and saidhinge member.

3. A motor vehicle radiator having a filler mouth, a filler cap, anS-shaped arm rigidly secured at one end to the under surface of said capand projectin laterally therefrom, a hinge member secure in said mouthbelow the outer end thereof, and a pivotal connecl10 tion betweentheother end of said S-shaped arm and said hinge member.

In testimony whereof I ailix my signature.
